As was said, the breather is to allow air to flow into the low-pressure crankcase under idle and part-throttle conditions. However, under wide-open throttle conditions, it vents high crankcase pressure resulting from blowby. The ideal situation is to run a "closed" system, or one that routes filtered air from the suction side of the air cleaner(s) to the breather. Problem here is most air cleaners used on Cobras don't provide a fitting to do this. Another approach would be to vent the crankcase to a firewall-mounted puke tank. Regardless of how it's done, the crankcase must be vented.
